Prerequisites
Visual Studio for Mac version 8.8 or later. Select the option to install .NET Core. Installing Xamarin is optional for .NET development. For more information, see the following resources:
- Tutorial: Install Visual Studio for Mac.
- Supported macOS versions.
- .NET versions supported by Visual Studio for Mac.
Create the app
Start Visual Studio for Mac.
Select New in the start window.
In the New Project dialog, select App under the Web and Console node. Select the Console Application template, and select Next.
In the Target Framework drop-down of the Configure your new Console Application dialog, select .NET 5.0, and select Next.
Type 'HelloWorld' for the Project Name, and select Create.
The template creates a simple 'Hello World' application. It calls the Console.WriteLine(String) method to display 'Hello World!' in the terminal window.
The template code defines a class, Program
, with a single method, Main
, that takes a String array as an argument:
Main
is the application entry point, the method that's called automatically by the runtime when it launches the application. Any command-line arguments supplied when the application is launched are available in the args
array.
Run the app
Press ⌥⌘↵ (option+command+enter) to run the app without debugging.
Close the Terminal window.
Visual Studio For Mac Integrated Terminal
Enhance the app
Enhance the application to prompt the user for their name and display it along with the date and time.
In Program.cs, replace the contents of the
Main
method, which is the line that callsConsole.WriteLine
, with the following code:This code displays a prompt in the console window and waits until the user enters a string followed by the enter key. It stores this string in a variable named
name
. It also retrieves the value of the DateTime.Now property, which contains the current local time, and assigns it to a variable nameddate
. And it displays these values in the console window. Finally, it displays a prompt in the console window and calls the Console.ReadKey(Boolean) method to wait for user input.NewLine is a platform-independent and language-independent way to represent a line break. Alternatives are
n
in C# andvbCrLf
in Visual Basic.The dollar sign (
$
) in front of a string lets you put expressions such as variable names in curly braces in the string. The expression value is inserted into the string in place of the expression. This syntax is referred to as interpolated strings.Press ⌥⌘↵ (option+command+enter) to run the app.
Respond to the prompt by entering a name and pressing enter.
Close the terminal.
Next steps
In this tutorial, you created a .NET console application. In the next tutorial, you debug the app.
-->This guide describes how to use Pair to Mac to connect Visual Studio 2019to a Mac build host. The same instructions apply to Visual Studio 2017.
Overview
Building native iOS applications requires access to Apple's build tools,which only run on a Mac. Because of this, Visual Studio 2019 must connect toa network-accessible Mac to build Xamarin.iOS applications.
Visual Studio 2019's Pair to Mac feature discovers, connects to,authenticates with, and remembers Mac build hosts so that Windows-basediOS developers can work productively.
Pair to Mac enables the following development workflow:
Developers can write Xamarin.iOS code in Visual Studio 2019.
Visual Studio 2019 opens a network connection to a Mac build host anduses the build tools on that machine to compile and sign the iOS app.
There is no need to run a separate application on the Mac – VisualStudio 2019 invokes Mac builds securely over SSH.
Visual Studio 2019 is notified of changes as soon as they happen. Forexample, when an iOS device is plugged in to the Mac or becomes availableon the network, the iOS Toolbar updates instantly.
Multiple instances of Visual Studio 2019 can connect to the Macsimultaneously.
It's possible to use the Windows command-line to build iOS applications.
Note
Before following the instructions in this guide, complete the following steps:
- On a Windows machine, install Visual Studio 2019
- On a Mac, install Xcode and Visual Studio for Mac
- You must manually open Xcode after installing so that it can add any additional components.
If you would prefer not to install Visual Studio for Mac, Visual Studio 2019can automatically configure the Mac build host with Xamarin.iOS and Mono.You must still install and run Xcode.For more information, see Automatic Mac provisioning.
Enable remote login on the Mac
To set up the Mac build host, first enable remote login:
On the Mac, open System Preferences and go to the Sharing pane.
Check Remote Login in the Service list.
Make sure that it is configured to allow access for All users, orthat your Mac username or group is included in the list of allowedusers.
If prompted, configure the macOS firewall.
If you have set the macOS firewall to block incoming connections, youmay need to allow
mono-sgen
to receive incoming connections. An alertappears to prompt you if this is the case.If it is on the same network as the Windows machine, the Mac shouldnow be discoverable by Visual Studio 2019. If the Mac is still notdiscoverable, try manually adding a Mac or takea look at the troubleshooting guide.
Connect to the Mac from Visual Studio 2019
Now that remote login is enabled, connect Visual Studio 2019 to the Mac.
In Visual Studio 2019, open an existing iOS project or create a new oneby choosing File > New > Project and then selecting an iOS projecttemplate.
Open the Pair to Mac dialog.
Use the Pair to Mac button iOS toolbar:
Or, select Tools > iOS > Pair to Mac.
The Pair to Mac dialog displays a list of all previously-connectedand currently-available Mac build hosts:
Select a Mac in the list. Click Connect.
Enter your username and password.
The first time you connect to any particular Mac, you areprompted to enter your username and password for that machine:
Tip
When logging in, use your system username rather than full name.
Pair to Mac uses these credentials to create a new SSH connectionto the Mac. If it succeeds, a key is added to the authorized_keysfile on the Mac. Subsequent connections to the same Mac will loginautomatically.
Pair to Mac automatically configures the Mac.
Starting with Visual Studio 2019 version15.6,Visual Studio 2019 installs or updates Mono and Xamarin.iOS on aconnected Mac build host as needed (note that Xcode must still beinstalled manually). See Automatic Macprovisioning for more details.
Look for the connection status icon.
When Visual Studio 2019 is connected to a Mac, that Mac's itemin the Pair to Mac dialog displays an icon indicating thatit is currently connected:
There can be only one connected Mac at a time.
Tip
Right-clicking any Mac in the Pair to Mac list brings up a contextmenu that allows you to Connect.., Forget this Mac, orDisconnect:
If you choose Forget this Mac, your credentials for the selectedMac will be forgotten. To reconnect to that Mac, you will need to re-enteryour username and password.
If you have successfully paired to a Mac build host, you are ready to buildXamarin.iOS apps in Visual Studio 2019. Take a look at theIntroduction to Xamarin.iOS for Visual Studioguide.
If you have not been able to pair a Mac, try manually adding aMac or take a look at the troubleshootingguide.
Manually add a Mac
If you do not see a particular Mac listed in the Pair to Mac dialog,add it manually:
Locate your Mac’s IP address.
Open System Preferences > Sharing > Remote Login on your Mac:
Alternatively, use the command line. In Terminal, issue this command:
Depending on your network configuration, you may need to use aninterface name other than
en0
. For example:en1
,en2
, etc.
In Visual Studio 2019's Pair to Mac dialog, select Add Mac..:
Enter the Mac's IP address and click Add:
Enter your username and password for the Mac:
Tip
When logging in, use your system username rather than full name.
Click Login to connect Visual Studio 2019 to the Mac over SSH and addit to the list of known machines. 2013 cfe exam prep course international edition.
Automatic Mac provisioning
Starting with Visual Studio 2019 version 15.6,Pair to Mac automatically provisions a Mac with software necessary forbuilding Xamarin.iOS applications: Mono, Xamarin.iOS (the softwareframework, not the Visual Studio for Mac IDE), and various Xcode-relatedtools (but not Xcode itself).
Important
- Pair to Mac cannot install Xcode; you must manually install it on theMac build host. It is required for Xamarin.iOS development.
- Automatic Mac provisioning requires that remote login isenabled on the Mac, and the Mac must be network-accessible to the Windowsmachine. See Enabling remote login on the Macfor more details.
- Automatic Mac provisioning requires 3GB of free space on the Mac to install Xamarin.iOS.
Pair to Mac performs necessary software installations/updates when VisualStudio 2019 is connecting to theMac.
Mono
Pair to Mac will check to make sure that Mono is installed. If it is notinstalled, Pair to Mac will download and install the latest stable versionof Mono on the Mac.
Progress is indicated by various prompts, as shown by the followingscreenshots (click to zoom):
Mono | Install Check | Downloading | Installing |
---|
Xamarin.iOS
Pair to Mac upgrades Xamarin.iOS on the Mac to match the versioninstalled on the Windows machine.
Important
Pair to Mac will not downgrade Xamarin.iOS on the Mac from alpha/betato stable. If you have Visual Studio for Mac installed, set yourrelease channel asfollows:
- If you use Visual Studio 2019, select the Stable updates channel inVisual Studio for Mac.
- If you use Visual Studio 2019 Preview, select the Alpha updateschannel in Visual Studio for Mac.
Progress is indicated by various prompts, as shown by the followingscreenshots (click to zoom):
Xamarin.iOS | Install Check | Downloading | Installing |

Xcode tools and license
Pair to Mac will also check to determine whether Xcode has been installedand its license accepted. While Pair to Mac does not install Xcode, itdoes prompt for license acceptance, as shown in the following screenshots(click to zoom):
Xcode | Install Check | License Acceptance |
---|
Additionally, Pair to Mac will install or update various packagesdistributed with Xcode. For example:
- MobileDeviceDevelopment.pkg
- XcodeExtensionSupport.pkg
- MobileDevice.pkg
- XcodeSystemResources.pkg
The installation of these packages happens quickly and without a prompt.
Note
These tools are distinct from the Xcode Command Line Tools, whichas of macOS 10.9 areinstalled with Xcode.
